JANUARY,    1890. 


The  Bulletins  and  BeporU  of  this   Station  are  mailed  free  to 
every  citizen  of  Connecticut  loho  applies  for  them. 


This  Bulletin  contains  some  corrections  of  errors  in  Bulletin 
No.  100,  besides  analyses  of  six  nitrogenous  Superphosphates, 
one  of  Cotton  hull  ashes  and  one  of  "  Hall's  Coral  Fertilizer." 


COKRECTIONS. 

On  page  19  of  Bulletin  No.  100,  the  nitrogen  and  potash  guar- 
anteed in  Chittenden's  Bone  Superphosphate,  No.  2504  are 
stated  to  be  3.3  and  4.5  respectively.  They  should  be  1.6  and 
2.0,  and  the  actual  composition  is  therefore  above  the  guarantee. 

On  page  26  the  valuation  of  H.  S.  Miller  &  Co.'s  Special  Po- 
tato Manure  No.  2603  should  be  136.82  instead  of  144.64  and  the 
Percentage  difference  8.7  instead  of  10.4.  The  valuation  is  be- 
low cost  instead  of  above  it. 

On  the  same  page  the  Percentage  difference  in  2521,  Crocker's 
Ammoniated  Wheat  and  Corn  Phosphate,  should  be  23.5  instead 
of  2.3. 

The  following  analyses  additional  to  those  in  Bulletin  No.  100 
have  been  made  within  the  past  year  on  samples  of  nitrogenous 
Superj^hosphates  and  Special  manures  which  were  di-awn  by 
Station  Agents.
